Drinking alcohol and having a rapid heartbeat can lead to sudden death. Drinking alcohol stimulates the heart and increases the contraction of the heart, and also stimulates the autonomic nerves of the heart and excites the sympathetic nerves, which can cause a variety of arrhythmias and other symptoms that can lead to sudden death. Drinking alcohol can aggravate cardiac arrhythmia in people who have arrhythmia, and if there is no arrhythmia, drinking too much alcohol can also cause arrhythmia, which can lead to myocardial hypertrophy, cardiac enlargement, cardiac insufficiency, myocardial ischemia, myocarditis, etc., and sudden death can also occur. It is best not to drink alcohol on a daily basis, especially if you have a heart condition. In addition, if you have any heart discomfort, you should seek medical treatment in time to avoid delaying your condition.
